just found a 10-10A at my "special little store", the salvage yard. as you can see its beyond filthy. got it to pull through but the rope wouldn't retract. when i took the covers off i saw why. that saw had never, ever been cleaned. every bit of oil impregnated dirt and sawdust ever moved by that saw was packed into every crevice. should have took pix but wasn't in the mood. took it to the car wash, picked the big stuff out, and pressure washed it. it cleaned up well but i did manage to almost obliterate the lettering on the top. duh!
looks like this thing sat in water for a good while. pretty good corrosion on the bottom of the starter cover and the bottom handle brace. the chain speaks for itself. the choke lever and the choke knob were both frozen (freed up now), the oil pump knob had been pulled out past the roll pin keepers (don't know how they did this but i haven't pulled the pin yet), the muffler only has the bottom half and not sure if it plugged, air filter is missing a little flocking but can prolly be fixed, fuel tank looks real clean, fuel line looks and feels good, once i got the starter cleaned and installed a new pull chord it seems to have decent compression. pulled the plug for a look see at the cylinder, what i could see looks okay. checked for spark but there wasn't any, big surprise.
this will never be a pristine saw but could be a decent runner and been wanting one for a while. but before i start acquiring and slapping parts on it i need to see if the ignition system components are okay and if i can get spark...
